It is often abbreviated as NUL (or NULL, though in some contexts that term is used for the null pointer). In 8-bit codes, it is known as a null byte . The original meaning of this character was like NOP —when sent to a printer or a terminal , it has no effect (some terminals, however, incorrectly display it as space ).
In computer programming, a naming convention is a set of rules for choosing the character sequence to be used for identifiers which denote variables, types, functions, and other entities in source code and documentation.
In object-oriented computer programming, a null object is an object with no referenced value or with defined neutral (null) behavior.The null object design pattern, which describes the uses of such objects and their behavior (or lack thereof), was first published as "Void Value" [1] and later in the Pattern Languages of Program Design book series as "Null Object".
Example of a spreadsheet holding data about a group of audio tracks. A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form. [1] [2] [3] Spreadsheets were developed as computerized analogs of paper accounting worksheets. [4] The program operates on data entered in cells of a table.
Can be used with the Travis-ci and Shippable continuous integration services (example), and integrates with MOcov to provide code coverage reports either offline or through coveralls.io(example). TTEST: No Gitlab repository [388] Works for both MATLAB and GNU Octave. Consists of an assertion framework and tools for refactoring.
Empty categories exist in contrast to overt categories which are pronounced. [1] When representing empty categories in tree structures, linguists use a null symbol (∅) to depict the idea that there is a mental category at the level being represented, even if the word(s) are being left out of overt speech.
For example, the sequence (with order type) of all positive odd integers followed by all positive even integers {,,,,,;,,,,,} is an ordering of the set (with cardinality ) of positive integers. If the axiom of countable choice (a weaker version of the axiom of choice ) holds, then ℵ 0 {\displaystyle \aleph _{0}} is smaller than any other ...
The empty string should not be confused with the empty language ∅, which is a formal language (i.e. a set of strings) that contains no strings, not even the empty string. The empty string has several properties: |ε| = 0. Its string length is zero. ε ⋅ s = s ⋅ ε = s. The empty string is the identity element of the concatenation operation
